I'm willing to bet that you've brought one of those famed Starfleet engineers who can turn rocks into replicators.
Kevan, in the Star Trek: Deep Space Nine episode "Rocks and Shoals"

We all know someone like that. Maybe they can't turn a rock into a matter replication device, but they know an app for every occasion. Or they take information in a tool like Evernote and publish it as a nice-looking web page or blog post.

But what makes someone tech savvy? Can they bend technology to their will, almost effortlessly? Are they like a polyglot when it comes to tech, able to easily and fluently move between technologies?

But do you really need to have that kind ability to be considered tech savvy?

No.

Being tech savvy is more personal than that. People I know who I consider tech savvy are people who understand the hardware and the software they use. That understanding is usually deep. Their knowledge often isn't as broad as that of some people, but it doesn't matter.

What matters is that they know what to use to get a job done. They know how to use those tools to do their work. They can use those tools efficiently and without much difficulty. And they can quickly adapt to new tools and techniques. That, I believe, is what's most important.

You don't need to be a ninja or an expert or a guru to be tech savvy. You only need to know what you need, what you use, and be able to adapt.
